The invention relates to a mechanically operated shearing machine for cutting blocks, rods and the like, and in which both the-upper and lower carriers are movable, beingadapted-to approach and recede from each other.

It has for its object to operate both of the carriers mechanically; and in such a manner that one of the two cutters is first the machine and not by upper carrier as in the machines shown in the foregoing-figures.

Fig. 4 is a vertical'section. of amachineof the type illustrated inFig.'13, and'shows, furthermore, the crank; shaft mounted in the transverse member which" is suitably connected'to the lower carrier, the connect ing rod being connected to the upper carrier. Figs. 5 and 6 are vertical sections illustrating further modifications in the method of mechanically moving said cutter carriers toward and away from each other.

Similar characters of referencedesignate corresponding parts throughout the several views.

Referringv now-to Fig. 1 of the drawings, a designates a suitable frame, I) a crank shaft adapted to berotateo by a suitable motor a through gearing 70, Z. The crank shaft mounted in a support such as a movable carrier 0 constituting the carrier for the, up

er cutter of the shearing machine. It will, owever, be understood that the crank -shaft and driving mechanism could also be mountmg machine but'in which connecting rod.

edin. the carrier. h of the'lower'cutter. This lower. carrier h is operated from a crank (Z, by means of the connecting rod 9. Both carriers move in suitable guides provided in the frame a; The downward movement of the carrier h in the support is limited, for example by means of a suitable stop n. On the rotation of the crank shaft in the directionof; the arrow, the upper carrier 0 descends until: it meets a resistance. It will thus come into contact with the block m and .remain in this position, whereupon on the further rotation of the crank shaft, the lower carrier h is raised and the block is cut'.. After. the cutting operation, the lower carrier? again descends until it comes into contact with the stopn. As its downward movementis then-prevented, the upper carrier c is moved back into-its original position.

liighftshows a shearing machine in which thecrank shaft b, the driving motor a and the intermediate gearing k l are likewise mounted in the upper carrier 0. The connecting rod 9 is not directly connected to the lower carrier,however, but to a transverse member h, provided in the upper carrier 0, which isconnected to the lower carrier by connecting rods k The downward movement of the latter in the frame a is limited by the stop n.

The machine illustrated in Fig. 3 is essentially the same as that illustrated'in Fig. 2, the difference being that the driving motor i and gearing are mounted on the frame a.

In the constructional form illustrated in Fig. 4.- the crank shaft 1; is mounted in, the transverse member h which is connected to the lower carrier in by connecting rods h, and the crank rod g is connected to the upper carrier 0. The crank shaft bis driven by the motor 2 mounted on the frame a through the gearing Z.

Fig. 5 shows a construction in which a toggle is connected to the upper carrier 0 and to a sliding member it connected to the lower carrier h by connecting rods 9 the toggle pin 2: being operated from the crank shaft 5 by a connecting rod g. According to the direction of movement of the pin 1), whether inward or outward, the cutters are moved toward or from each other. In this manner, therefore, during the outward movement of the pin, the upper cutter descends before the lower cutter rises, whereas on the inward movement of the pin 4) the operated from the crank shaft 6. through onnecting rod" g. When ther'ollersw are' lower cutter first descends and then the upper cutter rises. v

According to F 1g. 6, opposltely disposed inclined planes ware provided on the upper. carrier and on the slide it, which latter is connected to the lower carrier h.-' Between these planes are adapted to slide rollers :22
